Quantum Computers May Be Easier to Build Than Predicted

"A full-scale quantum computer could produce reliable results even if its components performed no better than today's best first-generation prototypes, according to a paper in the March 3 issue in the journal Nature* by a scientist at the Commerce Department's National Institute of Standards and Technology (NIST)."

"In theory, such a quantum computer could be used to break commonly used encryption codes, to improve optimization of complex systems such as airline schedules, and to simulate other complex quantum systems."
